Overall, it was good; the network worked everywhere, with no dropouts. Access to chat gpt and Google services was unavailable. I recommend getting a different eSIM card if you need chat gpt.

Before using this, I activated roaming on my phone from a network in Thailand, but when I arrived in China, I encountered problems that they couldn't resolve. However, after buying this eSIM, not only did it solve my internet problems, but it also allowed me to use the internet in China very quickly and cheaply. I think it's incredibly worthwhile, much better than roaming, and the internet is super fast.

This was my first time trying eSIM abroad, and I truly wish I'd discovered it sooner! Unlike before, I didn't have to go through the hassle of switching physical SIM cards, constantly worried about losing my original one. After purchasing it, I simply scanned the QR code to set it up, and I had internet access immediately upon landing – the signal was incredibly strong. I highly recommend it to anyone like me who values ​​efficiency and doesn't want to waste time!

The network card provided by this adapter in Osaka demonstrated a very stable and fast signal, and was easy to install. It is also very reasonably priced.
